B5-13 Development and Analysis of the Mathematic Model of Optimal Balance Point for the Air Source Heat Pump Water Chiller/Heater

In this paper, firstly, based on a summary and analysis of heating character of air source heat pump, two conceptions of optimal energy balance point temperature and optimal economic balance point temperature are put forwards, then the calculation method of them given and mathematic model corresponding to them developed, according to the weather data and the prevailing price of equipment and energy source corresponding to the potential regions, with which two types of balance point temperature corresponding to potential regions can be obtained. At last, different balance point temperatures and their application setting Beijing as an example are given. So how to choose the water heater/chiller units of air source heat pump can be directed.
